IMPROVEMENT IN WAGON-WHEEL LOCK.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, THOMASG. CLIFFORD, of Derby, in the county ot' NewHaven, and State of Connectilcnt, have invented a new Improvement inWagon-Wheel Lock; and I do hereby declare the following, when taken inconnection -with the accompany-ing drawings and the lettcrsiof referencemarked thereon, to be a. full, clear, and exact description of the same,and which said drawings constitute part of this specication,a,nd

representin- Figure 1, a View of the under side of a wagon, looking up.

Figure 2, a front end view; and in Figure 3, an inside view of one ofthe \vheels.

The object ot' this invention is to lock two or more ot` the wheels of awagon for the purpose of a. brake,

and consists in the arrangement ot' a bolt to each wheel, combined witha plate upon the wheehand with a mechanism for operating'the said bolts,so that at pleasure the said bolts may be thrown in the recesses uponthe wheel, and firmly lock and prevent the revolutions ot` the same.

In order to the clear understanding of my invention, as well` as toenable others to construct the same, l will proceed to a descriptionthereof, as illustrated in the accompanying drawings. l

A is the body of a. wagon; B the forward axle; C the rear axle; D theforward wheels; E the hind wheels, constructed and attached together inthe usual mal-nner, save that upon the inside of the huh ot' the wheelsis fixed a metallic plat-e, F, seen in fig. 3, provided with oneor-lnore holes, a,and upon the axles I place bolts, L, in such relativeposition to the wheels that when moved outwardthey will enter one ofythe holes in the said plate F, and are forced outward to so enter bysprings on vthe said'bolts, as seen in figs. I and 2, and when so thrownOutland entered into their respective holes in the wheel, therevolntioi'i of the wheel is entirely prevented.

To withdraw the bolts and permit th'e revolution of the wheels, Iarrange centrally upon the body, in some convenient position, a shaft,G, to which is attached a rope, d, chain, or similar device, extendingback and -connected to cach ot' the bolts, as seen in tig. l, so that byturning the said shaft as denoted. by the arrow in iig. 1, the severalbolts 4will be withdrawn from the wheel and lcare them perfectlyfree,and the shaft Gr, when so turned, is held in the position with the boltswithdrawn by a pa-wl and ratchet, fand z. Then, when at any time it isdesired to ar1est,the revolution of thc wheels, releasethe ratchet fromthe pawl, and the springs upon the bolts will quickly drive them outinto the plate npon the hub, and arrest the revolution ofthe wheels.This 'arrangement may be applied to one, two, or all ot' the wheels of avehicle, and is alike applicable to vehicles of two wheels.

Having thus fully describednny invention, what I claim as new anduseful, and desire to secure by Letters Patent, is-

The arrangement of' the bolts I, in combination with the plates F andthe shaft G, with i'ts ratchet h, constructed and arranged to operatesubstantially in the manner herein set forth.
